SECTION
PURPOSE OF AMENDMENT
1.1
Introduction
The Sanford North Water Reclamation Facility (SNWRF) is currently operating
under FDEP Operations Permit No. FLA0020141 which expires on April 7, 2008.
The SNWRF serves the City's residential, commercial, light industrial and rural
areas. The facility is classified as a "Secondary Treatment plus Filtration" Facility
using the activated sludge process and meets all Class I Reliability criteria. The
activated sludge system is designed and operated as a "complete-mix" activated
sludge process and uses a fine bubble ceramic disc aeration system to meet
mixing and oxygenation requirements and demands.
The unit operations and processes employed at the facility are divided into the
following categories:
Prima__.ry__Treatmen~t- including an Influent Structure with two mechanically
cleaned barscreens (N-inch spacing), back-up manual barscreen, a multi-
directional odor control system, and two "vortex" type grit chambers.
Secondary Treatment - "Complete-mix" activated sludge process including
aeration of the mixed liquor with fine bubble ceramic diffuser, final
clarification, and disinfection through the addition of "bulk" sodium
hypochlorite.
· ~ Treatmen__t- including tertiaryflltration (dual media traveling bridge
and DynaSand), chemical feed systems and high level disinfection.
· Biosolids Treatment- including sludge thickening (belt thickeners), aerobic
digestion and sludge dewatering (belt filter presses).
· Flow ~ _ including flow equalization in open, lined detention
basins and disinfection by chlorination.
2
In general, these unit operations and processes specifically treat the liquid and
solids trains to produce both an effluent that is acceptable for disposal to either the
reclaimed water distribution system or the St. Johns River and a "stabilized"
biosolids product that is acceptable for land application.
On January 31, 2005, the City of Sanford has received bids from local contractors
to build the "new" Sanford South Water Resource Center (SSWRC) on the
southeast side of the City. Wharton-Smith, Inc. of Lake Monroe, Florida was the
Iow, responsible, responsive bidder. Value engineering of the proposed treatment
facility is currently on-going to reduce costs and a Project Award should be made
by the end of March 2005. Following said Award, the Agreement between the City
and Contractor should be signed within three months followed by a Notice to
Proceed (NTP) with construction of the facility. The contract time to complete
construction of the SSWRC is approximately five hundred forty (540) consecutive
calendar days. In the interim, the current SNWRF will have to meet the wastewater
management needs of the City. Therefore, to ensure that the SNWRF has enough
treatment capacity, per FDEP regulations, to meet the service area wastewater
demands and to ensure that the City can continue to issue general permits and
accept wastewater flows as development continues throughout the City of Sanford,
a rerating of the SNWRF is required.
A meeting between the Cityof Sanford, CPH Engineers, Inc. and the Central District
of the FDEP occurred on February 7, 2005 concerning the rerating of SNWRF. The
District indicated that they would support a temporary increase in the permitted
capacity of the SNWRF to 8.0 MGD, until completion of the SSWRC, as long as a
detailed evaluation and rerating study was generated to support the proposed
increase.
1,2
purpose
This Amendment work is to generally provide professional engineering services to
support a request by the City of Sanford, to the Florida Department of
Environmental Protection, to rerate the Sanford North Water Reclamation Facility
from its present permitted capacity of 7.3 MGD to a higher capacity (8.0 MGD) on
an Annual Average Daily Flow (AADF) basis, while maintaining treatment
capabilities. This request shall be supported by the findings and results of a
detailed process evaluation of the SNWRF and actual "full-scale" operation of the
facilities and processes at elevated flow conditions for a three month period.
The ENGINEER shall provide all services required to complete each task in
accordance with regulatory requirements in effect on the date of execution of the
Agreement to the extent of the scope of work as defined and set out in this
Amendment. The ENGINEER shall perform professional services as hereinafter
stated in accordance with good engineering practices.
